Here's my Friday the 13th bad luck story: Rich came home and asked me if the truck drove OK for me. I said yes and why? He said the rear tire is flat. I said it wasn't flat when I got home. There was a piece of metal sticking out out the tread near the sidewall. Luckily for us, they were able to "plug" it. So our good luck story is that we didn't have to buy an expensive tire!
